Bpi Sports | 1.M.R OG Pre

BPI Sports 1.M.R The OG Formula is a classic high-stimulant pre-workout built around acute training intensity, not modern full-transparency clinical elegance. The strategy here is obvious: deliver a hard-hitting central nervous system lift with 300mg caffeine anhydrous, layer in additional stimulant and thermogenic character from yohimbe bark extract and cocoa-derived methylxanthines, then round out the experience with nootropic and neuromodulatory support from CDP-choline, GABA, taurine, and glycine. This is less a “pump-first” formula and more a legacy-style urgency-and-focus pre-workout designed to make you feel the session before the first working set begins.

The one fully disclosed performance anchor is caffeine anhydrous at 300mg. That is a high, effective dose in sports nutrition, enough for a pronounced increase in alertness, perceived energy, reaction speed, and training drive in most users. Because it is anhydrous, onset is typically fast and the effect profile is sharp rather than gradual. Niacin is included at 25mg as nicotinic acid. That dose is far below the 500-2000mg pharmacologic range used in lipid research, so this is not here for cholesterol effects; it is more likely present for energy-metabolism positioning via NAD/NADP biology and for the familiar warming or flushing sensation some users associate with pre-workout onset.

CDP-choline is one of the more interesting ingredients in the formula. Citicoline serves as a choline donor and supports acetylcholine synthesis, which matters for focus, motor drive, and mind-muscle connection. It is also a phospholipid precursor relevant to neuronal membrane health. The limitation is transparency: without the actual dose, you cannot confirm whether it reaches the commonly useful range. Still, from a formulation logic standpoint, pairing citicoline with caffeine makes sense because caffeine raises arousal while choline support can make that arousal feel more directed.

Taurine adds another smart layer. Taurine regulates cellular hydration, calcium handling in muscle, and neuromodulation, and human research supports acute doses in the 1-3g range for endurance-related benefits. It also pairs well with caffeine physiologically. Again, the issue is the undisclosed amount: it could be meaningfully supportive, or simply label decoration. Glycine and GABA are unusual but recognizable “texture” ingredients in this style of formula. GABA is the primary inhibitory neurotransmitter and oral GABA data is mixed, though some evidence supports stress modulation and a calmer edge. In a high-stim pre-workout, that means it may help smooth the stimulant experience rather than blunt it. Glycine is also neuromodulatory and metabolically useful, but its better-studied stand-alone dose is 3-5g, so an undisclosed inclusion is unlikely to reach that range.

L-carnitine tartrate and gamma-butyrobetaine ethyl ester HCl point toward a fat-metabolism and sweat-response angle. Carnitine helps shuttle fatty acids into mitochondria, while gamma-butyrobetaine is a carnitine precursor often used in aggressive stimulant formulas to amplify thermogenic feel. Yohimbe bark extract pushes the formula even further in that direction, especially for fasted or lower-insulin training contexts, but it also substantially increases the risk of jitters, elevated heart rate, and anxiety in sensitive users. Cocoa contributes theobromine-like stimulant support and mood lift. Inosine is the weakest evidence-based athletic inclusion here; older sports research does not support meaningful performance enhancement, and its modern research context is more neuroprotective than ergogenic.

As a system, the formula is built to hit three pathways at once: catecholamine-driven energy from caffeine and yohimbe, cognitive sharpness from caffeine plus CDP-choline, and session feel from taurine, GABA, glycine, cocoa, and niacin. The biggest limitation is the same one that defines many legacy formulas: most of the label is effectively non-transparent. You know the caffeine. You know the niacin. You do not know whether the supporting ingredients are robustly dosed or just included for effect on paper. Compared with current category leaders, that is a clear downside.

What should you expect? On day 1, expect a fast stimulant rise, possible warmth or flush from niacin, and a distinctly high-stim training feel that can border on aggressive if you are sensitive to yohimbe. Over 2-4 weeks, this is not a formula where you build toward a major saturation effect the way you would with fully dosed creatine or beta-alanine. The experience stays primarily acute: energy, urgency, focus, and thermogenic intensity each time you use it.
